Granted: 1998-12-15
Abstract: Divulgation d'un processus de préparation de compositions liquides viscoélastiques et thixotropes de détergents contenant des polymères plus denses, plus esthétiques et aux propriétés rhéologiques plus efficaces. L'agent épaississant thixotrope polymère est simultanément ajouté et mélangé sous forme de boue liquide à un prémélange à un taux de cisaillement allant de modéré à élevé pour neutraliser et disperser le polymère. Le produit est vidé de son air afin d'accroître la densité et d'améliorer l'aspect esthétique par mélange continu sous un taux de cisaillement allant de faible à modéré de la composition de boue liquide/prémélange. L'addition séquentielle et le mélange de la boue liquide/du prémélange avec un solvant organique, de l'huile, des antimousses et de la matière solide peuvent faciliter l'étape d'élimination de l'air.

Title: Catheter joint with restraining device
Inventor: BERG TODD A
IPC: A61M39/00
Filed: 1994-11-04
Granted: 2006-01-03
Abstract: An intravascular catheter of the type having an inner tubular member defining a lumen, an outer tubular member surrounding said inner member, and a support member mounted between the tubular members to provide rigidity to the flexible catheter. The support member comprises a wire braid, and in the preferred embodiment comprises a stainless steel wire braid which has been tempered or hardened to give it a significantly high tensile strength. This higher tensile strength affords significantly greater kink resistance to the flexible catheter as the lumen size is increased and the wall thickness is decreased, however, the high tensile strength wire braid has the disadvantage of tending to flare out during a bonding process when the catheter is joined to a tip, for example. In this invention, a retaining device is added to the end of the catheter to be joined, for preventing the flaring of the wire braid, whether the wire be of a high tensile strength or not.

Title: Device box support
Inventor: BOURASSA ALAIN
IPC: H02G3/12
Filed: 1995-07-05
Granted: 2002-05-14
Abstract: A support for mounting an electrical device box into an opening made in a panel. This support has an elongated bar-shaped member longer than the device box and two L-shaped members coplanar to and projecting from one side of the bar-shaped member. The distance between each one of the opposite ends of the bar-shaped member and the remote point of this bar-shaped member from which the remote L-shaped member projects is substantially equal to the height of the electrical box. In use, one can easily insert the bar-shaped member behind the panel through the opening made in the panel by first introducing one of the opposite ends of the bar-shaped member into the opening and moving this one end until the adjacent L-shaped member contacts the panel. Then, the support can be rotated so that the other opposite end of the bar-shaped member passes through the opening, such being possible because of the above mentioned distance selection. Fixation of the device box within the opening is subsequently achieved by folding back into the box the two L-shaped members.

Title: Enlarged cell foam and method of making same
Inventor: SUH KYUNG W
IPC: C08J9/00
Filed: 1993-12-07
Granted: 2002-05-07
Abstract: Disclosed is a process for making a closed-cell, alkenyl aromatic polymer foam structure having enlarged cell size. In the process, an alkenyl aromatic polymer material is heated to form a melt polymer material; a non-waxy cell size enlarging agent is incorporated into the melt polymer material; a blowing agent is incorporated into the melt polymer material at an elevated pressure to form a foamable gel; and the foamable gel is then expanded in a zone of lower pressure to form the foam structure. The enlarging agent is present in an amount sufficient to enlarge the stabilized cell size of the formed foam structure by 20 percent or more over a corresponding foam structure made without the enlarging agent. Further, the enlarging agent is incorporated in a quantity such that the formed foam structure has physical properties similar to the corresponding foam structure. Further, disclosed is a foam structure corresponding to the above.

Granted: 1999-09-14
Abstract: The invention provides a method and apparatus that conserves energy in the filling of a storage tank (1) with natural gas and dispensing natural gas from the storage tank to receiving tanks. The invention permits the refueling of gas receiving tanks at a fueling rate comparable to that achieved with liquid hydrocarbon  fuels, such as gasoline and diesel.  The apparatus includes the use of at least two compressors: a first compressor (2) and a second compressor (4), in series with and drawing less horsepower than the first, for compressing natural gas into a storage tank up to a certain pressure level that fills the tank, Upon demand for gas from the storage tank, the second compressor alone may be used to withdraw gas from the storage tank and supply gas at a fueling rate ro a receiving tank. When pressure in the storage tank drops to below a predetermined pressure level, the first compressor is brought on line to replenish gas in the storage tank to maintain the fueling rate through the second compressor

Abstract: A composite stent device comprises a shape memory alloy stent sleeve which is treated so that it can exert an outward force on a lumen in which the stent device is to be deployed, and a restraint element which restricts the maximum transverse dimension to which the stent sleeve can expand outwardly. The restraint sleeve can minimise damage to a lumen by a stent located within it. It can be arranged to allow the stent device to be deformed in a bending mode, for example when the lumen in which the device is located is subjected to a transverse flattening deformation, relying on the enhanced elastic properties of the shape memory alloy stent sleeve to recover to the open, generally rounded configuration.

Abstract: Terminals are inserted into groove portions of a first member and a covered wire is mounted on each of the terminals. Protrusions of a second member are engaged with the groove portions of the first member.  The second member is pressed so that the covered wires are pressed against press-fit blades of the terminal so as to attain electric conductivity.  By ultrasonic vibration in the pressing condition, the first member and second member are fused with each other.  At the same time, by ultrasonic vibration, the cores of the covered wires are fused with each other and the core and the press-fit blades are fused with each other. By the fusing of the cores mutually and the core and press-fit blades, the contact area is increased thereby decreasing contact resistance.

Title: Inhibiting completion of defrauding calls
Inventor: SMITH DAVID B
IPC: H04M15/00
Filed: 1998-02-09
Granted: 2000-09-12
Abstract: An arrangement for inhibiting the completion on defrauding calls. Calls to certain area codes are sometimes not subject to the kinds of regulations characteristic of U.S. based area codes. The result is that callers are charged an exorbitant fee (frequently several dollars per minute) without realizing that they are incurring such charges. In accordance with applicant's invention, a data base maintains a record of suspected telephone numbers and calls to the suspected area codes are checked to see if the call is to one of the suspected numbers. If so, the caller is warned and can disconnect before the call is completed. Advantageously, possibly for the payment of the fee, callers are saved from making calls with exorbitant charges.
